Ohad Nachtomy restates the main points of “Plenitude and Compossibility” with admirable fidelity and economy. His proposed revisions, based on the distinction between incomplete and complete substances and on the mind-relativity of relations, are intriguing additions to his earlier paper in Studia Leibnitiana and deserve careful consideration. Some brief remarks on the context of the problem, will, I hope, help to set the stage for the assessment of our various views.
